Central Chile has been identified as a unique ecosystem with high conservation priority because of its high levels of endemism and intensive anthropic pressure. Over a period of almost four decades, the monk parakeet has been successful in establishing and dispersing in urban Santiago, although little is known about its potential impact. Furthermore, nothing is known about its epidemiological risks towards animals or even humans. For this reason, we conducted the first parasitic survey of monk parakeets in Chile through capture, necropsy and thorough external and internal inspection of 92 adult individuals. Among these, 45.7% presented lice that were identified as Paragoniocotes fulvofasciatum, 1.1% had mesostigmatid acari and 8.9% had free-ranging acari. Among 89 parakeets, 19.1% had structures identified as Cryptosporidium sp. This study provides the first description of Cryptosporidium sp. in monk parakeets. Along with the presence of a mesostigmatid acarus in one parakeet, this serves as a public health warning, given that both of these parasites have zoonotic potential.
智利中部因其高度的特有性和强烈的人为压力，被认定为具有高度保护优先级的独特生态系统。在近四十年的时间里，和尚鹦鹉已成功在圣地亚哥市区定居并扩散，尽管人们对其潜在影响知之甚少。此外，对于其对动物乃至人类的流行病学风险也一无所知。因此，我们通过捕获、尸检以及对92只成年个体进行全面的外部和内部检查，首次对智利的和尚鹦鹉进行了寄生虫调查。其中，45.7%的个体身上发现了被鉴定为黄褐副角羽虱的虱子，1.1%有中气门螨，8.9%有自由生活螨。在89只鹦鹉中，19.1%的个体体内有被鉴定为隐孢子虫属的结构。本研究首次描述了和尚鹦鹉体内的隐孢子虫属。鉴于这两种寄生虫都具有人畜共患病的潜力，一只鹦鹉体内存在中气门螨这一情况也为公共卫生敲响了警钟。
